This week I was filming some content for YouTube with Supermicro in Santa Clara at an undisclosed location. As part of the project that folks will see next month, we had a NVIDIA BlueField-3 DPU on hand. I saw one at SC22, but I was told that was a Lenovo model. It turns out, that was incorrect. This sample was being used at Supermicro and it looks similar.
NVIDIA BlueField-3 400Gbps DPU Exposed
We originally took photos with this atop a 400Gbps ConnectX-7, NVIDIA H100 PCIe, and some Intel Data Center GPU Max 1100 series GPUs, but we realized that the Supermicro server all of those were in is not yet released. Luckily, we took backup photos on a white background.
Here we can see the same heatsink design that is offset from the optical cages to provide more airflow to high-speed optics. We also see that BlueField-3 is becoming a double-width model.
We have an 8-pin power connector here, so we expect this is a higher-performance model. This is also the second BlueField-3 with the blue glue. We are not sure if that color is a coincidence, but we hope it is not.
There is a lot of blue paste/ glue. These BlueField-3 cards are about as rare as Sumatran Tigers in the wild. We have still not been able to get one. As a result, we did not get to take the heatsink off.
These cards now have a nice backplate.w
We can see that this particular model was only produced in August 2022 and carries a D3B6 model. There is not a lot on the NVIDIA 900-9D3B6 out there.
Still, we can see a management port, time sync ports, then two 200GbE ports for a total of 400Gb/s.
Still, it feels like this is a significantly higher-power solution compared to the BlueField-2 DPUs that were single-slot solutions.
This week between the Marvell analyst event and preparing content for January 2023 launches, we were quite busy. A lot of the hardware we cannot show until next year, but this is one where it is a shipping product so we can show it. We just hope that NVIDIA releases more information on these beyond that they are 16 core Arm A78 PCIe Gen5 cards, with an onboard BMC and 16GB of onboard DDR5.
Unfortunately, this was not a case where I was able to take the DPU back with me to Austin.
